Analysis of the tribology performance of the high-strength composites

Using the hoop-lump experimental machine, I have studied three kinds of high-strength composites(s1, s2, s3) made in my company. They were rub against 45# steel separately under the conditions of dry-friction, water solution and 40# machine oil. The results show that under the condition ol oil-lubrication, the wear-proof performance of the high strength composites has been apparently improved. Their coefficient of friction dropped one order of magnitude than under the condition of dry-friction or water solution friction. Their rates of wear dropped 1-2 order of magnitude. S2 is the best one. Studying the tribology performance of S2 under the condition of coal mud, we found the coefficient of friction of S2 was below 0.2. Under the load of p=100N, its performance is better. The mechanical property test also shows that the high strength composites are superior All the tests show: The quantities, sizes and distribution of the strength composites have a better scope of appor-tion and proportion. More importantly, the results of the above test to tribology performance of the high strength composites will efficiently guide the production.
